2 Claims.

' -This invention relates to concrete construction, and has particularrelation to construction of the character describedLSpecialIy designedfor use in the erection of buildings.

An object of the invention is to provide specially designed units formedof concretious material and shaped to be fitted and anchored together ina novel manner as the units are erected into the building.

The invention comprehends novel type of Wall studding designed toreceive and support wall slabs which are anchored to the studding in asecure and novel manner.

With the above and other objects in View, the invention has particularrelation to certain novel features of construction, arrangement of partsand use, an example of which'is given in this specification andillustrated in the accompanying drawings, wherein:

Figure 1 shows a fragmentary top View of a wall constructed inaccordance with the invention and illustrating in dotted lines themethod of erecting the slabs.

Figure 2 shows a fragmentary side elevation of a wall constructed inaccordance with the invention.

Figure 3 shows a vertical sectional view taken on the line 33 of Figure2.

Figure 4 shows an, enlarged fragmentary cross sectional view of the walltaken onthe line 4-4 of Figure 2.

Figure 5 shows an enlarged fragmentary cross sectional view taken on theline 5-5 of Figure 2.

Figure 6 shows an inside elevational view of the wall slab, and

Figure 7 shows an end elevation thereof.

Referring now more particularly to the drawings wherein like numerals ofreference designate similar parts in each of the figures, the numeral 7I designates a suitable foundation preferably concrete and the upperside of whose outer margin has a counter sunk seat 2 to receive thelower margins of the lower tier of wall slabs hereinafter referred to.we

Supported on the foundation and suitably anchored thereto in therequired spaced relation are the upright studding 3 also formed ofconcretious material. The upright corner studding 3a is of approximatelytriangular cross sectional contour as illustrated in Figure 1. Each wallstudding, on each side, has a vertical outwardly facing shoulder 4extending from end to end thereof. Out beyond the correspondingshoulders 4, 4 each studding has, in each side thereof, a V-shapedgroove 5 extending from the upper to the'lower end thereof the outer andinner margins of the studding 3 present the outer and inner flat faces6, 1,, the former of which is approximately flush with the outer surfaceof the completed wall and to the latter of which the inside wall 8 maybe secured in any approved manner. The inner faces la, la of the cornerstudding 3a are aligned with the corresponding faces 1 and the outerside of the studding 3a may be given any desired shape, being showncurved in Figure 1. The outer wall is constructed of wall slabs 9 alsoformed of concretious material. The upper margin of each wall slab isformed with a longitudinal rib I0, from end to end thereof andpreferably V -shaped in cross section, excepting the upper margin of theslabs of the top tier, which are formed smooth as shown in Figure 2. Thelower margin of each slab is formed with a longitudinal V-shaped groovell extending from end to end of the slab and shaped to fit in to thegroove of the slab above.

One end of each wall slab is formed with a vertical V-shaped groove l2,and the other end thereof is formed with a vertical V-shaped rib l3,said groove and rib extending the full width of the slab. The inner sideof each slab has the longitudinal ribs l4, and the vertical ribs l5,cast integrally therewith to reinforce the slabs.

In erecting a vertical tier of wall slabs the grooves l2 and ribs 13 ofadjacent slabs are staggered, that is, the rib [3 at one end of the slabwill be arranged at the end opposite said rib of the adjacent slab aboveor beneath and the grooves I2 will be correspondingly alternated. Thisis illustrated more accurately in dotted lines in Figure 1. 1

In erection the groove 5, to receive the rib l3 as well as the adjacentface of the studding on each Side of said groove 5, will be'coated withpure cement as l6 and the corresponding ribbed end of the slab 9 willthen be inserted in place and its other end then swung around carryingthe grooved end of the Slab into abutting relation with thecorresponding shoulder 4, thus registering the groove l2 with theopposing groove 5, and the slab is then slightly lowered to seat the ribit beneath into the groove H of the slab above. The space inclosed inthe grooves 5, l2, will then be filled with pure cement I! asillustrated more accurately in Figures 4 and 5. Erection of the wall asabove indicated is proceeded with until completed and when the cementI6, I! sets the wall slabs will be firmly anchored inv place. Thestudding may be reinforced by suitable reinforcing rods l8, l8 which areembedded therein.

Tie rods H) are anchored to and upstand from the upper ends of thestudding as shown to provide convenient means for securing the superstructure on to the erected Walls.

The lower margin of the lower tier of wall slabs will be seated on theseat 2 of the foundation as illustrated in Figure 3.

The drawings and description disclose what is now considered to be apreferred form of the invention by way of illustration only, while thebroad principle of the invention will be defined by the appended claims.

What I claim is:

1. A construction of the character described comprising a foundation,spaced studding upstanding therefrom, outwardly facing abutments on eachside of the studding; the studding having vertical grooves outwardlyfromthe abutments, wall slabs fitted against the abutments and formingan outer wall and having ribs at one end to fit into the groove of onestudding and grooves at the other end to register with the groove of theother studding, said slabs having longitudinal ribs at one margin andcorrespondingly shaped marginal grooves at the other margin the studdingbeing reduced in thickness and extending inwardly beyond the outer walland having their inner margins formed with flat aligned faces againstwhich an inner wall may be secured in spaced relation to the outer wall.

2. Concrete construction comprising a foundation, spaced studdingupstanding therefrom, a vertical, outwardly facing shoulder on each sideof the studding, the studding having vertical grooves outwardly from theshoulders, wall slabs fitted against the shouders and forming an outerwall and having ribs at one end to fit into the groove of one studdingand grooves at the other end to register with the groove of the otherstudding, the inner faces of said slabs having horizontal andlongitudinal reinforcing ribs said studding extending inwardly beyondthe wall slabs and having aligned, fiat faces against which/the innerwall may be secured in spaced relation to the outer wall.
